3 Claims. (Cl. 179-63) This invention relates to coin controlledrecordapparatus.

An object of this invention is to provide an improved record playingsystem wherein a coin box and a loudspeaker may be disposed at onelocation and electrically connected to a central station, wherein therecords selected at the coin box are played and'then the sound istransmitted back to the loudspeaker.

Another object of this invention is to provide a central record playingstation wherein a plurality of'record playing members are located witheach'recordplaying member having a preselected record thereon and therecord playing member is actuated through dropping of a coin at a remotepoint.

A'furtherobject of this invention is to provide an improved recordtransmitting system which operates on the principle of telephone dialsso that the person dropping the coin in the coin box may dial a/codecharacter or number and when the dialing has been completed the selectedrecord will be played and the soundtransmitted back to the location ofthe coin box ,for audio transmission through a loudspeaker. With asystem of this kind the servicing of the record playing members issimplified and the usual automatic record playing devices .at presentpositioned in different locations will be eliminated.

To the foregoing objects, and others which mayhereinafter more fullyappear, the invention consists of the novel construction, combinationand arrangement of parts, as will be more specifically referred to andillustrated in the accompanying drawings, but it is to be understoodthat changes, variations and modifications may be resorted to which fallwithin the scope of the invention as claimed.

In the drawings: g

Figure 1 is a diametrical view of a record playing system constructedaccording to an embodiment of this invention, 7

Figure 2 is a fragmentary frontelevation of the coin box, r

Figure 3 is a schematic view of the electric circuits embodied in thisinvention,

Figure 4 is a schematic view of the pre-amplifier, and

Figure 5 is a schematic view of the power supply for the selector.

Referring to the drawing, the numeral l0 designates generally a relayexchange of the type at present in use in automatic or dial telephonesystems. 1 The relay means I0 is connected by means of a conductor 1 lto a remotely disposedcoin controlled selector box l2. The selector boxl2 includes a dial l3 of the typeat present in' use on dial telephones.The selector member [2 is also connected by means-oi a conductor [4 toaground or return conductor, so as to provide the complete circuit tothe relay" means Ill. The selector member I2 has positioned on the outerface thereof the titles l5 of records which it is desired to have playedand each title l5 has associated therewith code characters or numeralsl6 which are similar to the characters and numerals at present appearingon dial telephones and there may be any desired number of thesecharacters or numerals.

A loudspeaker IT .is positioned at the same location as the selector [2and is electrically connectedby means of a wire 18 to the relay means inand by means of a'wire [9 to the ground or return. The relay means H),which is positioned at the central location or station; has connectedthereto a plurality of record playing members,

generally designated as 20. Each record playing member 20 includesa-motor 2| having a turn table 22 operated thereby and on which a'recordis adapted to be positioned. .A tone or needle carrying arm 23 isadaptedto engage the record on the table 22 and'is connected by means ofconductors24 and 25 tofthe' relay means in and to the loudspeaker [1.The relay means In is of such construction that'when the dial I3 isturned in accordance with the codecharacters l6 a circuit will becompleted to a preselected motor 2| and to the tone ar'mor transmitter23, so that the sound picked up by the tone arm 23 will be transmittedback to the location through the conductors l8and Hi to the loudspeaker.

As shown in Figure 3 the central location is provided with a pluralityof record playing devices 20 which are connected to the selector I3. Therecord playing devices 20 each includes a motor 2| connected at oneside, as at. 26, to a source of current supply and connected at theother side. by means of a conductor '21 toa relay operated switch 28,which is normally biased to an open or circuit breaking position. Arelay. 29

actuates the switch 28 for moving the latter tov closed position havingone side 30 connected to the ground and the other side 3| connected toone of a series of contacts 32 arranged in a circle which are wiped by awiper 33 carried by an arm 34. The arm 34 is fixed to and insulated froma shaft 35. There will be a relay 29 and a switch 28 for each recordplaying motor and each relay will be connected to one of the contacts32. The tone arm 23 which engages the record on the "circuit 'breaking'positionand moved to" a table 22 when the latter is elevated byconventional elevating means and tone arm 23 is connected by means of apair of conductors 24 and 25 to a pre-amplifier, generally designated as36. The pre-amplifier 36 embodies a pair of amplifying tubes 31 and 38,shown in Figure 4, which are connected to a power transformer39 ofconventional construction having a suitable plug connector as shown. j

One side 4!! of the output side ofthe-pre-amplifier 36 is connected by"means of a fconductor 40 to one end of a primary transformer 4|. The

other end of the primary 4| is connected by con-1J1 ductor 42 to a wipercarrying arm 43, @150 mounted the other side of the output of the.pre-amplifr'ier 36.

The conductor 54 is connectedto the secondary 85 of the transformer 86 and a condenser 81 isinterposed in the conductor 54 adjacent one end of the secondary 85. Theother end of the secondary isconnected-by the conductor I 4 to theground ahda condenser 88 is intrp o'sed in the conductor 14. Theconductor I I is connected to the conductor 54 and is also connected toa resilient concounter-clo'ckwis 2.

The flow of current in-theprimary winding M, will induce a'pulsating current in 'the secondarywindingflflfi, which current will flow through the conductor lfl;thecontact 89', "thefcontact 92, to the 'conductor 93 andhence to theamplifier" at the receiving station." i J When the record has beencompletely played, the turntable 22 will move to reset position and willdepress the contact 64 against contact 66. Current will then flow fromthe power supply 39, through the conductor 34, the connectors 56 and thecontacts 55 and 58 into the arm 51 and through the conductor 59 to theclosed contacts 60 and 62. From the latter current will flow through theconductor 63, the closed contacts 64 and 66, the conductor 61, and theclosedycontacts 69 and 'IIto the conductor I2 which connects to thecontact I3 of the normally closed switch 14. From the contact I5 of theswitch I4, the current will flow through the coil I6 to ground, therebyenergizing the coil and moving the core TI and the pawl 82. Suchmovement of the core 1! will also efiect the opening of switch I4 sothat the pawl 82 will be reciprocated, thus rotating the shaft 35. Thisstep-by-step rotation of the shaft will continue until the arm 51 ispositioned as shown in Figure 3, that is, with the contact 58 disengagedfrom the contacts 55 in tacts II and 60 respectively. The selectorwillthen be in position for the selection of a turntable as,,-describedabove by dialing at I3.

The power supply for the selector includes, as shown in Figure 5, arectifier IUI of conventional construction connected to the secondaryI02 of a power transformer I03. The output of the rectifier II isconnected by conductors I04 and I05 to an outlet connector I86. A fuseIll! is interposed in one of the conductors between the rectifier IOIand the secondary I92 and a fuse ms is interposed in one of the powerlines leading to the primary I09 of the transformer I03 and having asuitable plug connector as shown. The conductor I04 is grounded, asindicated at III and a connector III which engages the connector I06 hasone terminal thereof grounded by a conductor I I2 and the othersconnected to conductors 84 and 48. Contact 98 of switch 96 is connectedto the main amplifier (not shown) on one side of the circuit of theamplifier, and wire 93 is also connected to the main amplifier. Theconnection of the contact 98 with the main amplifier is for the purposeof obtaining a relatively low voltage current to relay 52, whereby whenthe dialing operation has been completed and pin 90 is at rest, theswitch formed by the contacts 89 and 92 will be closed to wire 93 tosupply a current of higher voltage.
